Some Cisco appliances use a pre-standard version number for DTLS. We support
this as DTLS1_BAD_VER within the code.

This change fixes d2i_SSL_SESSION for that DTLS version.

This fixes another warning when config'd with no-ec

Reviewed-by: Dr. Stephen Henson <steve@openssl.org>

This is a partial back port of commit 5b430cfc

 to remove a warning when
compiling with no-ec.

Reviewed-by: Dr. Stephen Henson <steve@openssl.org>

When OpenSSL is configured with no-ec, then the new evp_extra_test fails to
pass. This change adds appropriate OPENSSL_NO_EC guards around the code.

The previous defaulting to TERMIOS took away -DTERMIOS / -DTERMIO a
bit too enthusiastically.  Windows/DOSish platforms of all sorts get
identified as OPENSSL_SYS_MSDOS, and they get a different treatment
altogether UNLESS -DTERMIO or -DTERMIOS is explicitely given with the
configuration.  The answer is to restore those macro definitions for
the affected configuration targets.

Conflicts:
	Configure

The rationale for this move is that TERMIOS is default, supported by
POSIX-1.2001, and most definitely on Linux.  For a few other systems,
TERMIO may still be the termnial interface of preference, so we keep
-DTERMIO on those in Configure.

crypto/ui/ui_openssl.c is simplified in this regard, and will define
TERMIOS for all systems except a select few exceptions.
